List of courses being offered in Winter Semester 2021

 

Special Centre for Nanoscience (SCNS) is a newly created inter-disciplinary research and teaching centre at JNU. The nanoscience related research topics pursued currently include ferromagnetic nanostructures, magnetic nanocomposites; microwave absorbers; nano-devices; magnetic nanoparticles based target-specific drug-delivery & treatment of cancer cells by radio-frequency-(RF) Hyperthermia; Giant-Magneto-Resistance bio-sensors; nano-biotechnology, bio-sensors, hybrid nanomaterials, anti-bio films, Electron microscopy, ferroelectric/ multiferroic nanocomposites, soft condensed matter, nanoscale interface, etc.

The Centre has faculty members with background in Physics, Electronics, Biology, Materials Science, and Electron Microscopy.

Presently, SCNS common instrumentation facility (CIF) has nanomaterial synthesis and nano-bio synthesis labs consisting of all basic characterization facilities including UV-vis,  Raman spectrophotometer,  BOD incubator, Laminar Hood, Dynamic Light Scattering, Zeta Potential Measurement, UV-NIR Spectrophotometer, Viscometry, Tensiometry, Potentiostat-Galvanostat, Cell culture facility, Fluorescence Spectrophotometer, Contact Angle Measurement, Elisa Reader, etc.

The Nano-electronics and microwave laboratory consists of DC and microwave probe-stations, microwave nano-devices testing facilities like; Vector Network Analyzer (Keysight Inc. PNA - 44 GHz), Spectrum Analyzer (Rohde and Schwarz Inc. - 40 GHz), Microwave Power Amplifier (Marki microwave) for absorbance testing, angle and temperature dependent variable-frequency Ferromagnetic Resonance (FMR) system. For nanostructure deposition we have multi-target RF Sputtering and thermal evaporation system. 750mJ Pulsed EXCIMER Laser based PLD ultra-high vacuum deposition system is under procurement process. We have photolithography and dry etching facilities for device fabrication. For in-vivo and in-vitro study, we have automated Radio-Frequency Hyperthermia system (MSI AUTOMATION, INC.) on mouse model and human cell-lines.

The Ferroelectrics and Multiferroics Characterization laboratory consists of Impedance Analyzer (20 - 120 MHz, Keysight Technologies), Sawyer Tower Ferroelectric/Multiferroic Hysteresis Loop Measurement Setup; Liquid Nitrogen Cryostat (77 – 800 K) etc.

Nanobio lab consists of human cell culture and storage facility (-20oC). We also have Fluorescence Microscope to monitor nanotoxicity and nano bio-interface. We have Multichannel Electrochemical analyzer to get electrochemical response of multianalytes on a single electrode. Beside this, we have Electro-spinning setup for synthesis of nano-fibres for biomedical application. 

Thin-film laboratory has a RF-DC magnetron sputtering system. Presently thin-films and bulk materials of functional oxides are being synthesized using mixed oxide and wet chemistry methods. Lead-free ferroelectrics and antibiofilms are currently being investigated. TEM investigations are an integral part of the research which will be carried out at AIRF of the university. Ion milling machine for preparing TEM samples is being installed at AIRF.

A wide range of analytical facilities including XRD, Transmission Electron Microscopy, Scanning Electron Microscopy, PPMS, Confocal Microscope, and other on-line cell imaging facilities are available at the Advanced Instrumentation and Research Facility (AIRF), which is a central facility of the JNU.

Programme of Study

The Center will eventually offer special topic courses in the area of Nanoscience.

Department Profile

A warm welcome to the modified and updated website of the Centre for East Asian Studies. The East Asian region has been at the forefront of several path-breaking changes since 1970s beginning with the redefining the development architecture with its State-led development model besides emerging as a major region in the global politics and a key hub of the sophisticated technologies. The Centre is one of the thirteen Centres of the School of International Studies, Jawaharlal Nehru University, New Delhi that provides a holistic understanding of the region.

Initially, established as a Centre for Chinese and Japanese Studies, it subsequently grew to include Korean Studies as well. At present there are eight faculty members in the Centre. Several distinguished faculty who have now retired include the late Prof. Gargi Dutt, Prof. P.A.N. Murthy, Prof. G.P. Deshpande, Dr. Nranarayan Das, Prof. R.R. Krishnan and Prof. K.V. Kesavan. Besides, Dr. Madhu Bhalla served at the Centre in Chinese Studies Programme during 1994-2006. In addition, Ms. Kamlesh Jain and Dr. M. M. Kunju served the Centre as the Documentation Officers in Chinese and Japanese Studies respectively.

The academic curriculum covers both modern and contemporary facets of East Asia as each scholar specializes in an area of his/her interest in the region. The integrated course involves two semesters of classes at the M. Phil programme and a dissertation for the M. Phil and a thesis for Ph. D programme respectively. The central objective is to impart an interdisciplinary knowledge and understanding of history, foreign policy, government and politics, society and culture and political economy of the respective areas. Students can explore new and emerging themes such as East Asian regionalism, the evolving East Asian Community, the rise of China, resurgence of Japan and the prospects for reunification of the Korean peninsula. Additionally, the Centre lays great emphasis on the building of language skills. The background of scholars includes mostly from the social science disciplines; History, Political Science, Economics, Sociology, International Relations and language.

Several students of the centre have been recipients of prestigious research fellowships awarded by Japan Foundation, Mombusho (Ministry of Education, Government of Japan), Saburo Okita Memorial Fellowship, Nippon Foundation, Korea Foundation, Nehru Memorial Fellowship, and Fellowship from the Chinese and Taiwanese Governments. Besides, students from Japan receive fellowship from the Indian Council of Cultural Relations.
